Abstract

An electric heating type rolling device comprises work rolls for rolling a metal strip, a power supply for generating a pulse current, a pair of upstream contact members which are disposed in a location before the metal strip passes through the work rolls, and a pair of downstream contact members which are disposed opposite to the upstream contact members in a location after the metal strip has been rolled by the work rolls and passed thereby. The contact members are electrically connected to the power supply. Each contact member includes a first contact portion contacting the metal strip, a flat portion which is extended from the first contact portion toward the work rolls while being spaced apart from the metal strip, and a second contact portion which is extended from the flat portion to contact the metal strip.

Description

technical field [0001] The present invention relates to a rolling device, and in particular to an electrothermal rolling device which improves the reduction rate by heating a metal strip with a pulsed current during a continuous rolling process. ), and prevent the surface oxidation of the metal strip due to excessive heating. Background technique [0002] In general, cold rolling refers to compressing and extruding a metal strip between work rolls at room temperature, while hot rolling refers to compressing and extruding a metal strip with simultaneous heating. [0003] The advantages of cold rolling are good dimensional accuracy and surface finish. However, cold rolling necessitates an annealing process, whereby the entire rolling process takes longer and lowers productivity. [0004] In the hot rolling process, the metal strip is heated in a furnace and then fed to a rolling unit. It is important to heat the metal strip to a certain temperature before rolling. When the...
